# Add DYNAMIC_ARCH control option to build.sh
## Summary
Add command-line options to manually control the DYNAMIC_ARCH parameter in
OpenBLAS compilation, allowing users to enable or disable dynamic CPU detection
at build time.
## Changes Made
### 1. build.sh
- Added two new command-line options:
- `--enable-dynamic-arch`: Enable dynamic CPU detection in OpenBLAS
(default behavior)
- `--disable-dynamic-arch`: Disable dynamic CPU detection in OpenBLAS
- Initialized `ENABLE_DYNAMIC_ARCH` variable with default value `'ON'`
- Added parameter handling for both new options in the argument parsing
section
- Passed `ENABLE_DYNAMIC_ARCH` variable to BE and Cloud cmake build commands
- Updated help documentation with usage examples and environment variable
info
### 2. be/src/olap/rowset/segment_v2/ann_index/cmake-protect/CMakeLists.txt
- Modified DYNAMIC_ARCH setting logic to support external
`ENABLE_DYNAMIC_ARCH` variable
- Added conditional check: if `ENABLE_DYNAMIC_ARCH` is defined, use its
value; otherwise, use default (ON)
- Maintained backward compatibility with existing behavior
## Usage
### Command-line options:
```bash
./build.sh --be --disable-dynamic-arch # Disable DYNAMIC_ARCH
./build.sh --be --enable-dynamic-arch # Enable DYNAMIC_ARCH (default)
./build.sh --be # Use default (ON)
